TOOL MOUNTING ASSEMBLY Filed April 10, 1967 Sheet 2 of 2 United States Patent 3,441,091 TOOL MOUNTING ASSEMBLY Glenn Helling, Alexander, N. Dak. 58831 Filed Apr. 10, 1967, Ser. No. 629,683 Int. Cl. E0213 3/ 76 U.S. Cl. 172-801 12 Claims ABSTRACT OF THE DISCLOSURE This invention relates to a tool mounting assembly and in particular to a mounting assembly for a tool useful in plowing, grading, farming and the like.

It is a feature of the invention to provide an improved tool mounting assembly which is sturdy, versatile, economical to manufacture, and which has few and relatively lightweight components.

It is a feature of the invention to provide a tool mounting assembly having arms connected to mounting means at substantial distances outwardly from the place of attachment of the mounting means to the vehicle frame, wherein there are provided force counteracting means secured to the frame and connected to the mounting means at each side of the frame at substantial distances outwardly from the place of attachment of the mounting means to the vehicle frame.

Other features of the invention will become apparent from the following detailed description in which:

FIGURE 1 is a top plan view and FIGURE 2. is a side elevational view of a tool mounting assembly and a tool, shown in conjunction with a fragmentary portion of a tractor;

FIGURE 3 is a sectional view taken along line 3-3 of FIGURE 1;

FIGURE 4 is a sectional view taken along line 44 of FIGURE 3;

FIGURE 5 is a sectional view taken along line 55 of FIGURE 3;

FIGURE 6 is a sectional view taken along line 66 of FIGURE 2;

FIGURE 7 is a sectional view taken along line 7-7 of FIGURE 1;

FIGURE 8 is a sectional view taken along line 8-8 of FIGURE 1; and

FIGURE 9 is a fragmentary side elevational view.

Referring now to the drawings, there is depicted a tool mounting assembly generally indicated at 10 shown to mount a tool generally indicated at 11. The tool 11 is shown to take the form of a blade.

The mounting assembly 10 is shown to include spaced apart arms 12 and 13 which are shown to be parallel to each other but this is not necessary. The arms can angle inwardly or outwardly as may be necessary or convenient depending primarily on the spacing of wheels 14 of the vehicle such as a tractor 15 with which the mounting assembly is used.

The arms 12 and 13 as disclosed in the present embodiment extend generally longitudinally with respect to the frame of the tractor 15. The arms 12 and 13 are identical in construction, each having a pair of tubular members 16 and 17 diverging from a hub or collar 18. A triangular plate 19 is welded to the marginal ends of the tubular members 16 and 17 and to the hub 18. The other ends of the tubular members 16 and 17 are welded to the marginal ends of an upstanding tubular member 20. A trapezoidal plate 21 is welded to the tubular members 16 and 17 and to the upstanding tubular member 20.

A generally transversely extending mounting member 22 having a tubular cross-section passes through apertures 23 and 24 in respective spaced apart brackets 25 and 26.

The brackets 25 and 26 are attached to the frame and if desired, as in this instance, to the transmission casing 27 of the vehicle. The transmission casing is considered part of the frame for purposes of the present invention. The brackets 25 and 26 are attached to the transmission casing 27 by threaded fasteners 28. To counteract the forces exerted by the arms 12 and 13 on the mounting member 22, members 29 and 30 are provided. The members 29 and 30 are of tubular construction. The members 29 and 30 are welded at their one ends to brackets 31 at an acute angle and are threadably and removably secured to the frame of the vehicle 15 by threaded fasteners 32. The other ends of the members 29 and 30 are welded to split collars 33 which are removably clamped to the member 22 by means of threaded fasteners 34. Braces 35 and 36 are connected to the frame at their one ends by the threaded fasteners 28 and at their other ends by threaded fasteners 39. The bracket 37 is welded to the member 29 and to the collar 33, whereas the bracket 38 is welded to the member 30 and to the collar 33. Although the member 22 is not indicated as being secured against rotation or shifting, the collars 33 and braces 35 and 36 prevent such rotation or shifting.

A transversely extending tubular member 39 is connected, as by welding, to opposed plates 40 and 41. The plates 40 and 41 are removably secured to respective plates 21 by threaded fasteners 42. Disposed between plates 40 and 41 and secured to the member 39 as by welding are follower members 43 and 44. The follower members 43 and 44 are guided by opposed vertically extending guides 45 and 46 so as to guide the arms 12 and 13 for vertical movement and to prevent the arms 12 and 13 or the tool 11 from shifting transversely. The arms 12 and 13 can pivot about the member 22 as indicated by the solid and phantom lines in FIGURE 2. A cable 47 is attached at one end to the frame of the vehicle 15, and at the other end to the transverse member 39 (FIGURE 8). A piston cylinder mechanism 48, secured to the frame of the vehicle 15 and operated by hydraulic fluid, has a cylinder 49 and a piston rod 50. A pulley 51 is rotatably connected to the piston rod 50. When the piston rod is extended the arms 12 and 13-, the tool 11, and the member 39 and the plates 40 and 41 are raised, and vice versa.

As indicated in FIGURES 1 and 2, the arms 12 and 13 are removably secured to the tool 11 by pins 52. The pins 52 extend through apertures in brackets 53 and through the tubular members 20. The brackets 53 are welded to ribs 54 and to angle irons 55 which are welded to the curved blade 56 of the tool 11.

As shown in FIGURE 9, an upright section or extension 57 can be selectively pinned to one or the other of the arms 12 and 13 so as to angle the blade relative to the direction of travel of the vehicle 15. The setion 57 has a pair of parallel, spaced apart tubular members 58 and 59, joined by upper and lower tubular members 60 and 61. Braces 62 are Welded at their ends to the corners of the rectangular section 57 formed by the members 58, 59, 60, and 61. Apertured plates 63 secured to opposed ends of the tubular member 58 straddle the tubular memher 20. One pin 52 secures the section 57 to the arm 12 or 13 to which the section 57 is to be connected. The section 57 is secured to the tool 11 by means of a pin 64 passing through the apertured brackets 53 and the tubular member 59.

Other embodiments and variations can be devised without departing from the spirit of the invention.
